While exploring the woods outside his suburban town, Dwight, a 21st-century teen, accidentally awakens Gothic princess Gretta, along with her court magician Baldric and scores of medieval villains.

Jacopo the Troubadour demands that Gretta relinquish her throne. Using his magical lute, he entrances the citizens of Woodside to do his bidding in his quest.

Dwight's community service project follows him home in the shape of an adorable puppy named Peanut. But Gretta and Baldric swear that the harmless puppy is something much more menacing.
